Write a single line of Python code that calculates the radius of a
circle with area 15 units and prints the value. The output should
just be the number that your code produces. Your code should include
the use of an expression involving division and exponentiation (to
compute the square root). Use the value 3.14159 for pi.

Which of these lines of code contain syntax errors? Once you fix
the syntax errors, the program (assume this has been typed into a
file and run in the Wing IDE) will still not correctly print the
area of a circle with radius 6.5. What two more changes are needed
to fixed these errors?

pi=21/7area=pi*r*rr=6.5r+5=r_newprint(area)

Assuming you start with $100 and earn 5% interest each year, how much
much will you have at the end of one year, two years and three years?
Write Python expressions to calculate these, using variables as
appropriate. We will demonstrate write the solution into a file
and run the file using the interpreter.

What is the output of the following Python code (when typed into a
file and run in the interpreter)? Try to figure it out by hand
before typing the statements into a file and running in the Python
interpreter.
